AUTOMATIC CARRIER.

To all fw 710m t may concern;

Be it known that we, GEORGE A. RAHMEYER and FRANZ P. RAHMEYER, citizens lof the United States, residing at Ansley, in the county of .Custer and State .of Nebraska, have invented certain new and useful lImprovements in rAutomatic Carriers, of which the following is a specification.

This invention relates to c'arriers,and the primary object" ofv the invention 1s to provide an improved dumping carrier which can .be

effectively used for transporting litter,`re

' moving or placing ensilage in silos, placing foodl in animaltroughs, or any other s1m'1.

lar purpose. Y Y

Another object of the invention is to `provide animproved overhead dumpin carrier, which when dumped willautoniatically returnto its normal position, thereby eliminating the labor and inconveniences 4generally associated with the closing of dumping cari'iers now on the market.

Another object of the invention is to provide an improved carrier box -whichlcan be readily dumped at any desired point'and the contents of the carrier box dropped directly below the same, thereby insuringvtheunloa ing-of the contents of the carrier at theV correct' place.

Y A further object of the `invention isy to 'pro-Vl vide a'iiimproved carrying box which can be eilectively used either -as a vertical hoist, or as -a horizontalsliding carrier, the carrier having means to permit the sameto 'be auto-V matically dumped, when 'used as' a horizontal carrier. l

A further object of the invention is tofpro-r videan improved dumping carrier embodying a 'pair of pivoted sections,`wl iieh are constructed exactly alike, and so connected,that

Y the 'same willmOVe together .andthereby permit the articles in the .Carrier to droppeddirectly belowY the same.

.A still further object of the inventionis to provide animproved c'arrierbox, ofthe abovecharacter which is durable and elif cient in use, one that is simple andl easy' to manufacture, and one which cany Vbeplaced upon the market at'areasonable cost. n

lilith these and other obie'cts in View, the

invention consists in the-novel construction,

Figure 3 is a side elevation of the .carrier when used'as a hoist, showing the .catches being releasedfor permitting the sections of the carriervto moveto their dumping posif tions, portions ofthe carriers being shown in section, `and `Figure 4 is an en d elevation of the carrier showing the same ina partly dumped position', parts of the carrier being shown in section. i i f Referring to the drawings 'in detail, where-V in.. similar referenceV characters designate corresponding parts throughout the several views, the letter'A generally :indicatesthe improved carrier, and B, thesupporting cable therefor which may be ofthe ordinary 4or any preferred construction and supported in'any manner; The cable B may be provid-YVv ed atY any desired point withV a dependin stop lug() as clearly shown in Figure 1 o the drawings, which forms means VAfor auto-y iiiaticallyfdumping the carrier Awhen'the carrier A reaches a predetermined pointy on.

the cable. I

The carrier A includes companion sections 6 and 7, which are constructed exactly. alike with the exception that` the section 6 is formed slightly shorter than the section 7 so yas to permit the sliding of the same in the .section Z when the carrier is being dumped. Each of the sections 6 and 7 in# cludes alongitudin'ally extending side wall S, end Walls 9y and `abottom wall `10 *andl when the sections 6 vand, f7 are in their opera,

tive positions in relation to each other, the same form a substantially- Lrectaii v.lar

shaped casing or boxwhich can be use for. transporting any desired material. TheV end'walls 9 of each section 6 7. are preferably. braced by angle ironsv A1l, but theseV angle'iro'ns may be dispensed A'with `if. not

found desirable or practical. The sections 6 and f7 may be further braced bydiagonally extending bars 12, which extend 'from on terminal of the angle irons tothe other.-

A supporting structure 13 is provided for the sections 6 and 7, and this supporting structure includes a longitudinally extending centrally disposed beam 147 which has its terminals provided with downwardly and outwardly inclined arms 14 and 15, and

vthese arms may be formed ol angle Viron it' so desired and either made integral with the su ortinCr beam 14 or se arate therefrom.

The lower terminals of the arms 14 and l5 extend beyond the ends of' the sections 6 and 7 and are secured as at 16 by means of suitarms 14 and 15 and 'form meansl for receiving the upper ends of the end bars 19wh'ich are bolted or otherwise secured to the end walls 9 of the section 7. Thesebars 19 as clearly shownl in Figures 2 and 4 of the drawingsV are locatedr flush with the outer edge of the end walls 9 of the sectionsf7 and extend slightly beyond the upper edge. of the same. These bars 1.9 prevent swinging movement of the sections 6 and 7 outwardly of the arms buty permit the sections to be. swung inwardly. The stops 18 are provided with openings20 which register with openings 21 in the upper ends olf the bars 19 whenthe sections 6 and 7 ,are in their operative carryingpositions, and these registering openings are adapted t0 receive the outwardly extending teeth 22 formed on the catches 23 which are pivotally-supported as at 24| on lugs 25 carried by the outer edges' of the longitudinally extending beam 14. These catches are adapted to be operated by means which will be hereinafter more fully described. Y Y

To insure that the sections 6 and 7 will operate synchronously a connecting bar 26 is-provided, which pivotally connects the end walls 9 of each section 6 and 7 tovgether. The connecting bars 26 have their upper ends pivotally connected as at 27 toA plates 28, which are secured vto the upper edgesot the side walls 9' of ythe section k6 intermediate its ends. The lower ends of theV connectingbars 26 are pivoted yas at 29 to vfaceplates k30 which are secured to the inner edges of the end walls 9 of the section. .7. 'Thus it will be seen that when one p `45 is usedfin lieu thereof which is bolted or 125 ofthe sections is swung inwardly the other willbe moved therewith. The dotted line position 'of this bar is clearly shown in Figure'2 ofthe vdrawings when the sections 6 and 7 are swung to theirl'ully opened posi- It can be seen that when the carrier A is loaded the sections 6 and 7 will have a tendency to-swing open owing to the weight oit the contents acting on the lower walls 1 0Y of the sections, and as soon as the catches 23 are released, these sections 6 and 7 will readily swing on the pivot pins 16 and permit the contents of the carrier to be dumped.

To insure that the sections 6 and 7 will return to their normal positions afterl thc contents of the carrier have been dumped7 springs 31 are provided which are of the V-shaped type and are provided with intermediate coils 32 so as to permitthe ready flexing of the springs when necessary. One terminal of the springs is secured to the side walls 9 of the sections 6 and 7 while the other'terminals are secured to the arms 14 and 15 of the supporting structure 13.V These arms 14.*and 15 may be connected togethcr by a cross'brace 33 if found necessary.

The carrier can. be effectively used, as stated either' -for hoisting the material or for tran'sportingmaterial in a horizontal plane,V and in Figure 1 the` carrieris-shownespe- 90 eially adapted for transporting material in a horizontal plane and in this figure theV supporting beam 14 is provided adjacent to its terminal with.v upwardly extending. supporting Ybrackets 34, which carry rollers 95 35 ywhich are adapted to engage thesupporting wire B. In this form the carrier is adapted to be automatically dumpedand levers 36 and 37 are VpivotedV intermediate their ends to a longitudinally extending U- shaped bracing member 38 which is secured to the longitudinally extending supporting beam 14. The levers 36 and 37 extend on the opposite sides of the transverse center of the carrier.andare'connected together by a rod'39 for synchronous movement. The lower terminals of the levers 36 and 37 have connected thereto flexible cables 41 and 427 y which are crossed intermediate their ends The cablesv have their opposite `vends connected Yto the latches 23. The terminals of the U-shaped bracing member 38 carry dcpending lugs 43 which support pulleys 44 for supporting the cables 41 and 42. 'It can" be seen that when the carrier is being moved 115 along the supporting cable B and one ot the levers 36 or 37 `hits against the depending ,stop 5, the catches will be operated, which will permit the sections and -7 to be swung open. Y

vIn Figure 3 ythe carrier is shown as being used `for hoisting articles and when used for thisk purpose the end brackets 34 may be dis-' ensedY with and the intermediate brackety adaptedto receive a hook or f the like 47130Vv mounted on a sui-table hoisting cable a8;

When used as fa hoist, cables 49 and l50 are used inlieu-of .the cables 41 and 42 and these cables have their innerfends connected directly to the lowerlterminals of the levers ,36 and 37 and are (,xtended straight tothe latches 23v and are not crossed like the cables ll1 and i2. These cables are also trained around the supporting pulleys 44 provided 4 for that purpose. A pullingrope or cable 51 may be secured l to either one of the levers 36 and 37 and it canbe'seen that when a pull is exerted on the rope 51 the levers will be moved outwardly as clearly shown in Figure 3 of the drawings which will effectively move the teeth 22 out of engagement with the registering openings formed in they stops 18 and the end bars 1 9. In Yoperation of the improved carrier, the material to be transported. is placed in the same, and the carrier is then moved along the cable B to the desired place and when one of the levers 36 or 37 comes into contact with the depending stop 5 the levers willl be swung on their pivots, thereby drawing the catches 23 from out of the registering openings and 21 thereby permitting the vrod 19 to move out of engagement Vwith the stop 18. This permits t-lie sections 6 and Z' to swing on the pivots carried by the arms 14 and 15 and release the material therein. As

soon as the material has been released, the sections 6` and 7 will immediately return to their normal positions owing to the tension of the springs 31. v

The form shown with the exception that when the carrier reaches the designated placeA Where it is desired to drop the material contained therein the rope or cable 51; is pulled which will operate the levers 36 and 37. The carrier illustrated in Figure 3-is especially adapted V :for removing or replacing'ensilage in silos a pair of companion sections, a supporting structure for the casing, means independently connecting the sections to the supporting structure :for swinging movement, a stop carriedby the supporting structure, means connecting the sections together vfor synchronous movement, aV rod carried by one of the sections arranged to engage said stop y in-Figure 3 isopeiated exactly like the form shown in Figure 1 supporting structure, a bar' carried b Vto `limit the swinging movement of the sections in one direction in relation to; the supporting structure, pivoted catches carried by the supporting structure and arranged to engage vsaid stop and rod to normally hold the sectionsrk against swingingv movement on the supportingV structure, and means for operating said catches.v
